Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1 and Figure 2 A transmission device 10 provided in an embodiment of the present utility model may include, for example: a first transmission member 100 and a second transmission member 200 .
[0030] Specifically, the first transmission member 100 is provided with a first connection end 102 for connecting to an external device, and the first transmission member 100 is used to make the first connection end 102 output a first motion. The second transmission member 200 is connected to the first transmission member 100 so that the first connection end 102 outputs a second motion.
[0031] Furthermore, the first motion is, for example, one of the motions such as acoustic wave vibration, rotational motion, and telescopic motion, and the second motion is, for example, one of the motions such as acoustic wave vibration, rotational motion, and telescopic motion that is different from the first motion.
[0032] Specifically, the first transmission member 100 is, for example, a motor that generates acoustic vibrations, and generates acoustic vibrations through high-frequency repeated vibrations, which is the first motion. In other embodiments, the first transmission member 100 may also be a motor that generates rotational motion or a motor that generates linear motion (i.e., telescopic motion), etc., and the present embodiment is not limited thereto. The second transmission member 200 is, for example, a linear telescopic motor, which is used to realize the telescopic motion of the transmission device 10, which is the second motion. In other embodiments, the second transmission member 200 may also be a motor that generates rotational motion or a motor that generates acoustic vibrations, etc., as long as the motion generated by the second transmission member 200 is different from the motion generated by the first transmission member 100, and the present embodiment is not limited thereto. Among them, the first transmission member 100 and the second transmission member 200 are connected together in an insertion connection manner. Of course, the connection manner may also be a spiral connection, etc., and the present embodiment is not limited thereto. The first connection end 102 is used to connect to an external device such as a toothbrush head. The first transmission member 100 enables the first connection end 102 to output sound wave vibration. The second transmission member 200 is connected to the first transmission member 100 to transmit the telescopic movement of the second transmission member 200 to the first transmission member 100, so that the toothbrush head can perform telescopic movement while achieving vibration.
[0033] In this embodiment, by connecting the first transmission member 100 with the second transmission member 200, the first connecting end 102 of the first transmission member 100 can perform a first movement (such as sonic vibration) and a second movement (such as telescopic movement), so that the transmission device 10 can achieve the coordinated work of sonic vibration and telescopic movement, that is, the transmission device 10 achieves the coordinated work of two different movements, sonic vibration can help loosen dirt and bacteria, and telescopic movement can better clean hard-to-reach areas, the cleaning ability of the transmission device 10 is improved, and the teeth can be cleaned more comprehensively and deeply. When the transmission device 10 is started, the first transmission member 100 and the second transmission member 200 work simultaneously, and the first transmission member 100 generates sonic vibrations, which can help loosen and remove dirt and bacteria on the surface of the teeth. At the same time, the telescopic movement of the second transmission member 200 is transmitted to the first transmission member 100, causing it to perform a telescopic movement. The telescopic movement allows the bristles to more effectively enter the pits and fissures between the teeth and the adjacent surface gaps, and clean the hard-to-reach areas. In this embodiment, the first transmission member 100 is connected to the second transmission member 200 to enable the first connecting end 102 of the first transmission member 100 to perform a first movement and a second movement, thereby improving the cleaning ability of the transmission device 10 and allowing the teeth to be cleaned more comprehensively. In addition, since the first transmission member 100 and the second transmission member 200 are integrated together, the transmission device 10 achieves improved cleaning ability while having a simple structure. The components in the transmission device 10 are compactly arranged, which makes the transmission device 10 miniaturized, making it more convenient to carry and use, ensuring the cleaning function while being convenient for users to hold, further improving the user experience.
[0034] Reference Figure 2 The first transmission member 100, for example, includes a first transmission member body 110 and a transmission shaft 120, and the transmission shaft 120 is connected to the first transmission member body 110. Figure 1 , Figure 2 , Figure 3 and Figure 5 The transmission shaft 120 has a first connection end 102 and a second connection end 101 opposite to the first connection end 102. The first transmission member body 110 is, for example, a motor that generates sound wave vibrations, and is used to generate sound wave vibrations to drive the first connection end 102 of the transmission shaft 110 to swing. Figure 6a and Figure 6b In this embodiment, the first transmission member body 110 is configured to allow the rotating shaft 120 to swing left and right. In other embodiments, the first transmission member body 110 can also be configured to allow the rotating shaft 120 to swing up and down, and this embodiment is not limited to this. The transmission shaft 120 is made of, for example, a high-strength metal material to withstand large torque and axial loads during the transmission process. The transmission shaft 120 is used to transmit power and torque, and is used to transmit the sound wave vibration generated by the first transmission member 100 to the toothbrush head. The transmission shaft 120 is connected to the first transmission member body 110. The transmission shaft 120 can be connected to the first transmission member body 110, for example, by penetration or integral molding. This embodiment is not limited to this. Refer to Figure 5 The second connection end 101 is connected to the second transmission member 200. The second connection end 101 of the transmission shaft 120 can, for example, pass through the second transmission member 200. The transmission shaft 120 transmits the telescopic movement generated by the second transmission member 200 to the first transmission member 100, so that the first connection end 102 outputs sonic vibration and telescopic movement to the outside, making the cleaning power of the transmission device 10 more comprehensive.
[0035] In this embodiment, when the transmission device 10 is working, it drives the toothbrush head to swing and move forward and backward in the axial direction. For example, the first transmission member 100 generates sonic vibrations through high-frequency repeated vibrations and transmits them to the brush head. The sonic vibrations can help loosen and remove dirt and bacteria on the surface of the teeth. The second transmission member 200 drives the connection structure and the brush head to perform telescopic movements through telescopic movements. The telescopic movement enables the bristles to better enter the pits and grooves between the teeth and the adjacent surface gaps, thereby improving the cleaning effect. Through the integration of the first transmission member 100 and the second transmission member 200, the transmission device 10 can realize the left and right movement of the bristles, making the cleaning more comprehensive and detailed.
[0036] Reference Figure 5 The second transmission member 200 , for example, includes a second transmission member body 210 and a telescopic member 220 . The telescopic member 220 is connected to the second transmission member body 210 . The telescopic member 220 is sleeved on the second connection end 101 and fixedly connected to the second connection end 101 .
[0037] The second transmission member body 210 is, for example, a linear telescopic motor for generating telescopic motion, and the telescopic member 220 is, for example, a part with telescopic performance for achieving length change or telescopic motion. The telescopic member 220 is extended or contracted as needed to achieve the desired motion effect. In this embodiment, the telescopic member 220 is movably connected to the second transmission member body 210, and the second transmission member body 210 generates a linear telescopic motion, driving the telescopic member in the first direction (such as Figure 5 For example, when the second transmission member body 210 is working, the linear motion generated by the second transmission member body 210 is transmitted to the telescopic member 220. Since the telescopic member 220 is movably connected to the second transmission member body 210 and fixedly connected to the second connecting end 101 of the transmission shaft 110, the telescopic member 220 and the transmission shaft 110 move back and forth in the first direction relative to the second transmission member body 210. This linear motion is transmitted to the first transmission member 100 and the first connecting end 102 through the transmission shaft 110, so that the first connecting end 102 outputs sonic vibration and telescopic motion to the outside, making the cleaning power of the transmission device 10 more comprehensive.
[0038] Reference Figure 3, the transmission device further includes, for example, a connecting structure 300. The connecting structure 300 connects the first transmission member 100 and the second transmission member 200. In this embodiment, the connecting structure 300 includes, for example, a housing. In other embodiments, the connecting structure 300 may also include, for example, a locking device such as a buckle block, a buckle or a thread lock to ensure that the first transmission member 100 and the second transmission member 200 are fixedly connected to the connecting structure 300 to enhance the stability of the device, which is not limited here. A cavity is formed in the housing, and the first transmission member 100 and the second transmission member 200 are inserted into the cavity. For example, the first transmission member body 110 is arranged in the housing, and the first connecting portion 301 of the housing is fixedly connected to the second transmission member body 210. The first transmission member 100 can move relative to the housing. During operation, due to the vibration of the first transmission member 100, it will move left and right or forward and backward relative to the housing, and the telescopic member 220 of the first transmission member 100 will drive the first transmission member 100 to move forward and backward relative to the housing. The housing has a first connection portion 301 away from the first connection end 102, and the first connection portion 301 is connected to the second transmission member 200. The first connection portion 301 is the portion of the connection structure 300 that connects the second transmission member 200, and the first connection portion 301 is used to provide sufficient strength and rigidity to withstand the load and stress during the connection process when the first transmission member 100 and the second transmission member 200 transmit force and torque to each other, so as to maintain stability. In this embodiment, the connection structure 300 can provide additional stability to ensure the reliable connection between the first transmission member 100 and the second transmission member 200. In this way, during the use of the transmission device 10, no accidental loosening or separation will occur, thereby improving the reliability and stability of the device.

For example, the first connecting portion 301 is an engaging protrusion, and the second engaging portion 230 is a connecting groove. The engaging protrusion is, for example, a rectangular protrusion (not shown in the figure) or a protrusion of other shapes, and the connecting groove is, for example, Figure 3 The rectangular groove shown in the figure or other shapes matching the card and the protrusion. The rectangular groove is engaged with the rectangular block column, so that the stability of the transmission device 10 can be improved, and the adverse effect of instability when the user uses the transmission device 10 can be avoided, and it is also helpful to increase the convenience of disassembly and assembly. In other embodiments, the second transmission member 200 is provided with a snap-fitting portion, and the first connecting portion 301 is provided with a groove corresponding to the snap-fitting portion, but the present embodiment is not limited thereto.

In the transmission device 10, the first elastic return member 400 can be configured to provide an elastic force, so that when the second transmission member 200 cancels the force acting on the first transmission member 100, the first transmission member 100 can be restored to its original position, such as the middle position in the shell, under the action of the first elastic return member 400, thereby enhancing the stability of the transmission device 10, helping to maintain the normal working state of the transmission device 10, and providing a more comfortable and efficient cleaning experience.

[0043] Among them, the second connection part 302 is located in the part of the connection structure 300 relative to the first connection part 301, and the limiter 500 is connected to the second connection part 302. The limiter 500 is connected to the second connection part 302 by, for example, bonding, welding, etc., and can also be integrally formed with the shell, but this embodiment is not limited to this. The limiter 500 is used, for example, to limit or control the range of motion of the first transmission member 100, to prevent the first transmission member 100 from exceeding the designed limit position during operation, and to prevent the relative movement between the first transmission member 100 and the second transmission member 200 from exceeding a predetermined range. This embodiment ensures the stability and reliability of the first transmission member 100 and the second transmission member 200 by setting the limiter 500, to prevent them from exceeding the predetermined position, thereby maintaining the normal working state of the transmission device 10.

Setting the connection structure 300 as a two-shell structure is conducive to increasing the convenience of disassembly and assembly. The first shell 310 and the second shell 320 form a cavity for accommodating the first transmission member 100. The first shell 310 and the second shell 320 are, for example, made of high-strength metal materials such as steel to provide sufficient strength and rigidity to withstand the load and stress during the connection process.
